What's cooking Gordon Ramsay?

Chef Gordon Ramsay is cheating on his devoted wife Tana, according to a report in The News of the World (NOTW) on Sunday.

Ramsay — who revels in his family man image — is said to have begun his affair with blonde Sarah Symonds seven years ago. Ramsay allegedly had a 75-minute tryst with his mistress three days ago at a London hotel.

The 42-year-old chef has become a multi-millionaire promoting "Brand Ramsay" as a loving husband and father of four. NOTW alleged that during the time he has been seducing Symonds, the foul-mouthed chef had made numerous claims about his fidelity to his wife of 12 years Tana, 33.

In 2006 Ramsay was voted Celebrity Father Of The Year and in 2007 the Ramsays were named Celebrity Family Of The Year. Fans are used to seeing his children, aged from five to nine, appearing on his TV shows and in magazine interviews.

In October 2007, Symonds cemented her reputation as a "professional mistress" by writing the book: Having An Affair? A Handbook For The Other Woman. It made such an impact that she was a guest on The Oprah Winfrey show.

Symonds also had a year-long affair with Jeffrey Archer around the time of his failed bid to become the Mayor of London in 2001.
